- --------------------------------------------------------------------------

Package        : ppxp
Vulnerability  : missing privilege release
Problem-Type   : local
Debian-specific: no
CVE ID         : CAN-2005-0392

Jens Steube discovered that ppxp, yet another PPP program, does not
release root privileges when opening potentially user supplied log
files.  This can be tricked into opening a root shell.

For the old stable distribution (woody) this problem has been
fixed in version 0.2001080415-6woody1 (DSA 725-1).

For the stable distribution (sarge) this problem has been fixed in
version 0.2001080415-10sarge2.

For the unstable distribution (sid) this problem has been fixed in
version 0.2001080415-11.

We recommend that you upgrade your ppxp package.
